This is where that Severus Snape had two daughters that are identical twins and he couldn't tell them apart. When Nina Snape died after her two twin daughters were born, Severus kept his twin daughters secret until it was too late. Even the Dark Lord knew

Diana looked around and found a girl that looked oddly familiar. "Rosie? Is that you?" Diana asked.

Kaitlyn looked behind her and she huffed. Great, just my luck. Kaitlyn thought then turned back around to the front and opened her book waiting for class to start. She was tired of seeing this girl and it was getting on her nerves.

Kaitlyn moved quickly and put her books between her and Diana. "Sorry, the tables full." Kaitlyn snickered.

"Kaitlyn, would you get a grip?" Diana told her sister.

Meanwhile in the office:

Snape was looking inside the prophecy to find out what his secret daughter that ran away before the twins were born. When the prophecy shows that there is a daughter of his lurking around somewhere in this castle. As the bell rang, Snape sighed and put the prophecy inside his desk and came out of his office and sat in the desk. All he seen was his twin daughters and the Weasley girl. "Please open your books to page 324, we're reviewing of what we just learned last weekend."

Kaitlyn and her twin sister didn't talk after that. They both took out their books and opened it to page 324. Kaitlyn decided to take out her parchment and her quill and wrote down a note. She wrote her sister saying 'Why do you have to be such a twit?' Then gave it to her sister.

Diana took the note and read it. Then wrote back, 'Its really none of your business. What is going on with you? You're always different.' Diana wrote and handed it back to Kaitlyn.

Snape sees the note passing, "Diana and Kaitlyn. Please come up here and bring the note." He said.

Kaitlyn and Diana went up to where their father is and gave the note to their father as well. As he read it, he glared at Kaitlyn. "Kaitlyn, you are having detention with me this afternoon. And after that, you're grounded to your room." Snape said.

Kaitlyn stared at her father, "WHAT!" Kaitlyn screamed. "THE BLOOD HELL I WOULD!" She screamed at her father. "I HATE YOU! I'M SO OUT OF HERE!" Kaitlyn screamed and then grabbed her stuff and stormed out of the classroom.

Diana and Snape stared in disbelief. Snape stared at the Weasley girl. "You are dismissed. Diana please stay behind. I have to talk to you." Snape told her then left towards back inside his office.

Diana nodded as her father left. Then she turned towards Rose. "I'm really sorry Rose, something is different about my sister and my father wants me to talk about it. So I'll talk to you later hopefully." Diana said then left towards the office.

Diana went inside the office door and seen her father stand at the window. "Would you like to know why your sister Kaitlyn changed?" Snape asked her. Then turned to look at Diana with sad almost crying eyes.

Diana sat down in a chair and listened. "Yes dad." Diana said.

Snape was quiet for a moment, then spoke. "Your sister has changed because, because she had a, a Dark Mark on her right arm." Snape said finally.

Diana gasped.

"Don't worry Diana. I also have something to tell you. You and your sister isn't the only sister you got. Before you and Kaitlyn was born. Your other sister, Eliza Snape. Is her name."

*Is down by the Slytherin Common room waiting to find out if Scorpius was in there the Boy came out and said no but he just left to go visit Professor Snape so She went back towards the potions classroom*

Snape heard the office door open. He turned around and seen Scorpius, "Hello Scorpius. What did you need?" Snape said, then looked at his daughter. "Diana, you may go." Snape said and then turned towards his desk.

Diana nodded, "Yeah, he's in there with my father." Diana said then sat down in a desk thinking about what to do. Diana never knew that she and Kaitlyn had an older sister and she's around in this castle somewhere. Diana turned to look at Rose and smiled.

Scorpius looked at Rose. He smiled at her. "Snape told me I could join the Quidditch Team. I approved." Scorpius said. Then put his hand on Rose's shoulders. He looked at Diana and nodded and then left.
